Application filed March 24, 1898.

To 'aZZ whom it may concern.-

Be it known that LWILLIAM MCCALL, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Slidable Hinged Window-Sashes; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in windows, and is especially applicable to the hinging of the sashes to sliding. strips upon which they are carried and which strips are vertically movable in the grooves or channels between the stops and parting-strips.

It consists in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a view of my window, the lower sash being turned inwardly. Fig. 2 is a horiz'ontal section through the two' sashes. Fig. 3 is a view of the locking-plate in the pulleystile of the hinged side. Fig. 4 shows the groove in the slide. Fig. 5 is a section through the lock on the opposite slide. Fig. 6 is a detail view of the latch-carrying plate. Fig. 7 is a View of the key.

A is the window-casing, having the usual outside and inside stops and parting-strips, between which the upper and lower sashes B and B are slidable; I In order to allow these sashes to be opened inwardly, so that both outer and inner surfaces can be easily reached for cleaning or other purposes, the sashes are hinged upon one side to vertically-slidable strips C, these strips having a sufficient width in one direction to be essentially equal to the thickness of the window-sashes and a sufficient thickness in the other direction so that they project outside of the stops and partingbeads, and the sashes arehinged to these strips byhinges D, so that they may be opened about their hinges when both sashes have been drawn down to the bottom, the'lower sash being opened inwardly first and the upper sash being opened directly behind it. It

will be manifest'that when the sashes are thus opened it will be necessary to lock the sliding strip C in some manner, so that the weight of the sash will not pull them out of their posi- Serial No. 674,980. (No model.)

strips on the opposite side against which the sashes close, so that when the strips are released from the sashes they will not be violently pulled up to the top of the window by the counterweights which are connected with them. Y

The weights are of the usual character and are connected by cords E with the edges of the slidable strips C in the same manner that they are ordinarily connected with the edges of the sashes when the latter are simply slidable.

In order to lock the sliding strips to which the sashes are hinged, I have shown plates F secured against the pulley-stiles in the bottoms of the grooves or channels in which the sashes slide, one near the bottom and the other near the top of the lower sash and the other pair in a similar position with relation to the upper sash, so that when the upper sash is drawn down to its lowest point they will also be engaged. These plates have proj ecting from them a rib f, which forms a head with channels between it and the plate F.

G G are plates which are screwed upon the inner faces of the sliding strips C in such a position with relation to the fixed plates F and their projecting portions f that these plates G will slide into the grooves formed beneath the heads f when the'sashes are drawn down to the bottom, one pair of plates G sliding behind the head f at the bottom of thepulley-stile and the other pair simultaneously engaging the corresponding part near the upper end of the sash. These plates being thus held by the grooves beneath the heads f will lock the sliding strips C f rmly in place on the pulley-stiles, and whenthe window-sashes are disengaged and turned inwardly the weight of the sash pulling upon the strip C will not-pull it out of place.

In order to insure the proper engagement of the plates G when the sash is drawn down,

I have shown the upper ends of the heads f 5 and also of the shank beneath as being tapered or V-shaped at the top, as shown at f so that the lower ends of the plates G will easily slip into place when the sash is drawn down. This allows the sash when closed in its normal position to slide up and down without any action on the part of these holding-plates; but as soon as the sash is drawn down to the bottom,where the plates and lugs engage, it can thereafter be swung open without pulling the slides out of place. It will be understood that the whole weight of the sash being supported upon the slides on this side there will be no occasion for any other means for holding them down, as only one set of weights are connected with these slides, and the entire weight of the sashes is sufficient to at all times hold them down while the sashes are disconnected from the opposite side. Upon the opposite side, however, it is necessary to positively lock the slides C in place before the sashes are swung away from them, else the counterweights would immediately and violently pull them to the top of the casing. For this purpose I have shown segments II, the inner angles of which are pivoted so that the outer periph cry of each is turnable about its pivot J. These segments are pivoted in metallic easings I, which are secured to the outer edges of the sliding strips 0 in such a manner that the segments may be turned to either engage interiorly the sashes or exteriorly the pulleystiles against which the slides are movable. \Vhen turned to engage the sashes, the sliding strip 0 and the sashes are practically locked and movable together, so that they slide up and down as a single piece when the sashes are in their normal and slidable position. \Vhen the sashes are to be opened, they are first pulled down, as before described, and when at the bottom the segments are in line with the openings or sockets formed in the pulley-stiles against which the slides move. The segments can then be turned a part of a revolution about their pivots, and when either one is thus turned the edge which was previously engaged with the sash will be disengaged therefrom, the turning of the segment projecting the other edge into the socket in the pulley-stile, and this will hold the slide 0 in engagement with the casing, so that when the sash is disengaged and opened outwardly from it the slide will thus be prevented from flying up to the top of the casing. The means for operating this segment are the hollow pivot or sleeve J, passing through the interior angle of the segment and journaled in the case in which the segment turns, and a key L, the shank of which fits in the sleeve. The end of the sleeve which projects toward the inside of the window from the segment II has a section cut out, as shown, and a pin or lug K projects from the shank of the key into this slot. When the key is inserted into the hole in the hollow sleeve or pivot J and turned, it will move freely until the lug K strikes the side of the sectional opening, after which a further turning of the key will carry the segment [I with it. The segment thus turned will engage either with the sash or the casing, as previously described. In order to lock the segment in either of these positions after it is engaged with the sash or the casing, I have shown sockets 0 made in the periphery of the segment, and these are engaged by a latch I, carried by a spring-pressed plate Q, lying between the segment H and one side of the easing and movable radially with relation to the sleeve J. IV hen the segment has been turned until either of the notches arrives beneath this latch, the latch will be forced into it by the spring and hold the segment. In order to disengage the latch from the segment, it is necessary to first withdraw the latch from the socket with which it has been engaged. This is effected by the movement of the lug K upon the key-shank. The end of the lug engages the end of the sliding plate Q, and when the key is introduced the first turning moves the plate and disengages the latch I, because by reason of the cut-out section in the sleeve J the lug is allowed to move a certain distance before it commences to turn the segment. By this construction a single key acts, first, to unlock the latch and leave the segment free to move, and, secondly, to turn the segment until it reaches the desired position to lock it in the opposite direction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'

1. In a hinged and slidable window-sash of the character described,the slidable strips vertically movable against the pulley-stile having the cords of the counterbalance-weights connected with the strips, means for locking the strips to the sashes or disengaging the strips from the sashes and locking them to the casing, consisting of V-shaped segments having pivots at their interior angles, casings within which said segments are turnable about the pivots, said casings being let into and secured to the sliding strips so that the segments move through the strips to one side to engage the pulley-stile, a key adapted to engage and turn the segments and having a lug and a locking device substantially as shown by which each segment is held in either position of engagement, said locking device engaged and actuated by the lug on the key before said lug acts to turn the segment.

2. A device for locking the sliding strips of hinged slidable window-sashes consisting of segments pivoted in casings which are secured to the strips so that the segments may be turnable through the strips to engage the windowsash upon one side and the pulley-stile upon the other side, a tubular pivot-pin journaled in the casing and having a section cut out from one side, a key, the shank of which enters the tubular pivot, with a lug projecting into the cut-out section to turn the segment in either direction when the key is turned and the lug strikes either end of the slot, a radially-slidable plate and a latch carried there- In witness whereof I have hereunto set my by adapted to engage netches in the ends of hand. the segment to lock 1t 111 elther posltlon of WVILLIAM MCCALL engagement, said slide being moved to disen- 5 gage the catch by the first turning of the key Witnesses:
